The function that ran into Accumarray was in Steve's article [1]. This is a very flexible build-in function, so there is no M file, see implementation code. began to understand the comparison, looked at the example to know what meaning. MATLAB's help [2] says so: Accumarray groups elements from a data set and applies a function to each group. A = Accumarray (Subs,val) creates an array A by accumulating elements of the vector Val using the elements

substrings of length, and there is a total of length method. The length method overrides all of the substrings that need to be found.For each segment, a substring of length can be treated as a cell that is no longer split, using the sliding window algorithm (Slide window algorithm) to find a target substring that meets the criteria in linear time , O (n/length) complexity, where n is the length of S. For a total of length distributions, it takes time O (length * n/length) = O (n).algorithm Impl

In Oracle, MERGE statements are used to merge update and INSERT statements. The MERGE statement is used to query another table based on the connection conditions of one table or subquery. The join condition matching is updated, and the INSERT statement cannot be executed. This syntax only requires one full table scan to complete all the work, and the execution efficiency is higher than INSERT + UPDATE. Merge into is also a dml statement. Like other dml statements, you need to end the transaction
